System Intialization - Alcatel-Lucent 7210 SAS M Configuration Manual

System Intialization

System Intialization
When the system is powered ON, it executes the bootstrap image, for example, the boot.tim file,
from the file system which is located on a non-removale flash device (cf1:) that is built in to the
7210 SAS-Series router. The boot.tim file is the image that reads and executes the system
initialization commands configured in the Boot Option File (BOF). The default behavior is to
initially search for the boot.tim file on cf1:. This behavior cannot be modified. On 7210 SAS-M
and 7210 SAS-X, If the boot.tim file is not present, or is not a valid loadable file, the Golden
bootstrap image is loaded by the bootrom. The Golden bootstrap image is equivalent to a boot.tim
file except that it is present outside the file system and can be updated and checked by means of
special CLI commands. On 7210 SAS-T and 7210 SAS-R6, if the boot.tim is not available in cf1:\,
it looks for a boot.tim in other locations (cf2 and uf1).
The system is shipped with the following on different platforms:
When the system executes boot.tim, provision is given to the user to modify the BOF manually
and save it or to boot using existing BOF. The bootstrap image then processes the BOF file present
in the flash as explained in
On systems that are shipped without a BOF file, when the system is powered ON for the first time,
When the system is powered ON for the first time, there will be no BOF in the system. Hence,
provisions are given to create a new BOF file or alternatively get the BOF file from the network.
There are two options:
•
•
More details on how to use the various system boot options is available in the platform Installation
guide.
On systems that ship with the BOF file, user can use the starter BOF or interrupt the boot process
to manually edit the BOF to change it contents and create a new BOF. More details on how to do
this is available in the platform specific Installation guides.

Boot by manually creating a BOF file (manual boot).
Boot by retrieving the BOF file from the network, using DHCP to get the network location
of the BOF file (auto init). Auto-init is the default boot procedure if there is no manual-
intervention during the first-time boot of the node.
